RadGrid Sorting and Expanding problems

[T]

I have following problems with hierarchical RadGrid control:

1)When I click on some column header (in order to sort according to this column), data will sort ascending. After second click on the same column, nothing will happen!

2)When I click on expand button (in order to expand DetailTableView), the DetailTableView will expand. After second click on another one expand button, new DetailTableView will expand but the original expanded DetailTableView will contract! (but when I click on the same expand button, the expanded DetailTableView will not contract). 

Simply sorting and expanding of DetailTableViews works not correctly.

Can you please help me?

Hello,

Did you receive any javascript errors on the page?

Hello Pavlina,

I have recieved no JavaScript errors.

But I found out, that these problems probably relates with fact, that we use this control inside KENTICO project - on control, which is derived from 'CMSAbstractWebPart'.

I have tried to use RadGrid in new empty WebSite, and in this case it works correctly.

Can you please help me? Do you have some experience with using this control in KENTICO?

Thank you. 
Thomas
